Making a NAND Backup

In case anything should go wrong in the later process and your Wii U ends up bricked, restoring a previously made NAND backup can fix it.

Instructions

?> The Wii U NAND is (depending on your model) either 8GB or 32GB. As a result of this, to create a full backup of your console's NAND, your SD Card has to be larger than the size of your NAND. If you do not have a large enough SD Card, you can skip the optional MLC section which includes save files and game data and is not needed to recover most types of bricks.

?> Restoring a NAND Backup on the Wii U requires additional hardware and micro soldering skills.
However, making a NAND Backup is always useful, so please do not skip it.
Your NAND Backup is unique to your system. Backups from other consoles won't work.

  1. Navigate to nanddumper using the GamePad and press A to launch it.
  2. Use the Wii U GamePad's D-Pad to enter the following configuration:
    • Dump SLC: yes
    • Dump SLCCMPT: yes
    • Dump MLC: optional
    • Dump OTP: yes
    • Dump SEEPROM: yes
  3. Press the A button to start the dumping process.
  4. When the process completed, power off your Wii U, take your SD Card out of the Wii U and plug it into your PC.
  5. The files will appear on the root of the SD card.
  6. To make sure you don't lose the files, copy the slc.bin, slccmpt.bin, seeprom.bin, otp.bin (and if you chose to go with a full backup, every mlc.bin.part) file to your computer.
  7. Delete the files from your SD Card to free up space.

?> If the PayloadLoader is already installed into the Health and Safety Information app and your console is already autobooting it, you do not need to continue following the guide.
